SHADE-HOLDER FOR ELECTRIC LAMPS.

SPECIFICATION forming part of Letters Patent N o. 667,324, datedFebruary 5, 1901.

Application filed September 17, 1900. Serial N o. 30,324. (No model.)

T0 all whom, it nfl/ay concern.:

Be it known that I, GEORGE M. LANE, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Shade-Holders forElectric Lamps; and I do hereby declare the following to be afnll,clear, and exact description ofthe invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention provides a shade-holder designed most especially forelectric-arc lamps, although adapted for general use to secure a globeor like part to any style of lamp, electric or otherwise, in such amanner as to admit of the globe being easily and quickly placed inposition or removed and which will prevent its casual displacement whenproperly positioned.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreifecting the result reference is to be had to the appended descriptionand drawings hereto attached.

While the essential and characteristic features of the invention arenecessarily susceptible of modification, still the preferred embodimentof the invention is illustrated in the accompanying drawings, in which-Figure l is a side elevation of the holder, showing the shade or globein position, the upper portion of the shade being broken away. Fig. 2 isa front view of the holder as it appears when seen from a point about ata right angle to Fig. l. Fig. 3 is a top plan view. Fig. 4 is aperspective view of a modification.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

, The holder consists, essentially, of a plate l and spring-actuatedclamps 2, pivotally connected with opposite ends thereof. The plate l isof oblong formation and is provided at opposite ends with pairs of ears3, between which the clamps 2 are pivotally mounted. The plate iscentrally apertured, as shown at 4, and a shank 5 is pendent therefromin line with the opening and is adapted to be received in the holder ofthe ordinary arc-la 1n p,thereby adapting the latter to be inclosed. Theplate is recessed in its top side, as shown at 6, to form a seat for theshade or globe 7, whereby the latter is held from lateral displacement.

The clamps 2 are of similar formation and correspond in width to theplate l, so as to extend approximately from one side thereof to theother. In edge view the clamps are approximately of elbow form and aredisposed with their long arms vertical and their short arms horizontaland facing inward, so as to engage over the outer iiange at the lowerend of the shade or globe 7. These clamps 2 are mounted upon rods 8,supported at their ends in corresponding ears 3. Lugs 9 projectoutwardly in opposite directions from the jaws of the clamps 2, and theends of coil-springs lO are connected therewith, said springs serving tocause the jaws of the clamps to engage over the base portion of theshade, globe, or analogous part and hold it upon the baseplate 1. Theedges of the jaws are made concave to conform approximately to thecircular outline of the shade, globe, or kindred part to be held uponthe plate l, thereby enabling the jaws to obtain an extended bearingagainst the sides of the part to be secured thereby. The springs 10, inaddition to their function of causing the jaws to engage posi tivelywith the shade or globe, likewise serve to prevent lateral displacementof the shade, since they extend across the space formed between the jawsand are adapted to bear against opposite sides of the shade or globe.The pendent portions of the clamps when pressed inward against thetension of the springs l0 effect a corresponding outward movement of thejaws, thereby permitting the shade 7 or analogous part either to beplaced in position upon the plate l or to be removed therefrom, asdesired. When the clamps are released from the pressure of the hand, thesprings 10, regaining their normal position, move the jaws inward towardeach other, so as to engage over the base portion of the shade andretain it in position.

In the form of holder shown in Fig. 4 the clamps are cut away in linewith the rods 8, so as to receive coil-springs 10, which are mountedupon the rods 8 in the spaces .11,

formed by cutting away the clamps; as stated One end of each spring 10ais secured to theA rod 8, upon which it is mounted, and the opposite endis attached to the adjacent clamp 2. The normal tendency of the springsl0 is t0 force the clamps of the jaws inward in a manner similar to thesprings l0 and for a like purpose. The latterconstruction is morecompact and for this reason is preferred in many instances.

Having thus described the invention, what is claimed as new isl. In aholder of the character described, a base-plate having oii'standing earsat opposite ends, rods supported by said ears, clamps pivotally mountedupon the rods, and springs adapted to force the jaws of the clampsinward and toward each other, substantially as set forth. v

2. In combination, a plate having' a recess in its top side, acentrally-disposed opening, and a pendent shank 5 in line with the saidopening, and spring actuated clamps pivot ally connected to oppositeends of the plate, as andfor the purpose set forth.

3. In combination, a base-plate, clamps .pivotally connected to oppositeends 01"' said plate, and springs connecting the jaws of vthe clamps andspanning` the space formed between them and adapted to supplement y'theaction of the jaws and prevent lateral displacement of the shade, orpart placed .upon the plate, substantially as set forth.

GEORGE M. LANE.
